Dear Erman,

Our Client wishes to create daily snapshot from ODA box at either VM Level or Database (ACFS Snapshot) level.

My Query is:
1. If creating VM level snapshot backup, does this VM snapshot contain all the O/s and also DB (database) snapshot and how fast is it to take the snapshot on VM level and how fast it can be restored if the DB and Application sizes is nearly 1TB.

2. How useful is ACFS snapshot and can this ACFS snapshot be taken incremental depending on the CDC or Archive logs etc?

Thanks & Regards
Viswa
